>Riding that level of cultural and social change is not something people know how to do, and might well look dauntingly impossible when you also have a family to feed. So to see people making six figures on the coasts talk down their noses about mobility and "intestinal fortitude" (from one of your comment's siblings) is, honestly, pretty galling.

It's morally galling, yes. However, if we're talking politics, "Obey the free market or die!" is exactly what these very factory workers have been screaming at the entire rest of the country, in every single federal election year. This is what voting for unfettered capitalism means, and there's a level of moral gall in saying, "Capitalism for thee, social democracy for me".
